Definitions

  • the invention relates to a method and a device for communication with a system, in particular for operating and monitoring an automation system in industrial production.
  • Output devices or in other words observation devices, are, for example, indicator lights, alphanumeric or graphic displays, which inform the system operator about the current system status.
  • Input devices, or in other words control devices are e.g. Switches, rotary knobs or keyboards for alphanumeric input that enable the operator to influence the system.
  • communication devices In the conventional way, for the purpose of communication between the user and the system, so-called operating and monitoring devices, hereinafter referred to as communication devices, are fixed to the system itself or e.g. installed in the production hall in which the system is located.
  • a typical communication device has a handy housing on which input and output devices are arranged. The data exchange with the system or with its control takes place via a permanently installed connection line.
  • wired communication devices With very large or difficult to access systems, wired communication devices can no longer be handled.
  • mobile, ie freely movable, battery-operated communication devices that communicate wirelessly with the system and handle the data exchange with the system via radio connection.
  • the wireless communication devices must be equipped with safety functions that can be used to achieve a safe system status in the event of danger.
  • safety functions For radio-based communication devices, this is usually the so-called stop function.
  • the stop function is usually implemented using a safety button on the communication device. Pressing this button causes the system to stop immediately.
  • So-called approval functions can also be provided on the communication device.
  • the enabling function is triggered by a safe, two- or three-stage enabling button in order to move safety-critical movements in the pressed or half-pressed position of the button, e.g. trigger the movement of a part of the system or the movement of a robot arm.
  • a safe, two- or three-stage enabling button in order to move safety-critical movements in the pressed or half-pressed position of the button, e.g. trigger the movement of a part of the system or the movement of a robot arm.
  • the mobile communication device is normally logged off from the system in a controlled manner without the radio link being broken, whereupon this is again via e.g. Permanently installed wired communication devices are operated and monitored, but continue to operate normally without triggering the safety shutdown.
  • Known communication devices also have indicators for the state of charge of the battery. The operator himself has to draw the right conclusions from this, e.g. End the operation and monitoring of the system in good time with the help of the mobile communication device and log it off properly in order not to activate the system's own safety functions.
  • the object of the invention is to specify a method and a device in order to enable the operator to use the full battery capacity as far as possible and yet to avoid the system downtime caused by battery draining.
  • the object is achieved by a method for communicating with a system, in particular for operating and monitoring an automation system in industrial production.
  • a battery-powered communication device is available for exchanging data with the system.
  • the state of charge of the battery is determined and the expected remaining life of the communication device is determined from the state of charge.
  • a measure is taken in the system or in the communication device.
  • the determined remaining running time of the communication device that is to say the time that its user still has to communicate wirelessly with the system, has determined a meaningful quantity which can be further processed in the system or in the communication device.
  • the time for example in minutes, provides much more useful information than the knowledge of the state of charge of the battery, for example in percent.
  • measures can be taken in the system or in the communication device. These can e.g. consist in reducing the power consumption in the communication device by reducing the brightness of a display attached to it. Or as a measure with sufficient remaining runtime, the user is not shown any information about the charge status or remaining runtime. This does not distract him because he does not have to worry about the state of charge at this time. Other measures may be to give the user an acoustic, visual or mechanical warning, e.g. by honking, flashing or vibrating the communication device when the remaining time is approaching zero.
  • Specifying a threshold value for the remaining term and taking the measure when the threshold value is reached is particularly advantageous.
  • the threshold value can be set individually for each system. If, for example, the operator only needs a little time to complete any work with the communication device, the threshold value can be kept very low, so that as a rule, that is to say for most of the battery charge levels, the operator is never confronted with measures.
  • the operator is not bothered, for example, for remaining terms above the threshold value, the functionality of the communication device is fully provided. The operator does not need to process any additional information.
  • An advantageous measure is to indicate the remaining time to the operator.
  • the display can be permanent or only below a given threshold for the remaining term. The remaining time in minutes is displayed, for example, on an alphanumeric display on the communication device.
  • the user can estimate much better whether or which work he can still properly complete with the help of the communication device in the remaining remaining time before the battery is completely empty. The user can thus use the almost full operating time of the communication device and still log off the communication device to the system in good time, i.e. surrender control of the mobile communication device properly, thus avoiding the automatic plant safety shutdown of the entire plant.
  • the functionality of the communication device is changed depending on the remaining time.
  • the functionality of the communication device is changed depending on the remaining time.
  • the user can never use the communication device to trigger functions on the system that cannot be locked within the determined remaining term. This prevents the user from triggering a process that takes too long, which would inevitably lead to the activation of the system-side safety functions due to the radio contact being torn off after the battery has been drained. The user cannot inadvertently activate such processes.
  • a plurality of threshold values are specified and the functionality of the communication device is successively changed when each threshold value is reached.
  • targeted user guidance can be implemented on the communication device, in which, for example, its functionality is gradually and increasingly restricted, for example with a decreasing remaining term.
  • the operator has to limit himself more and more in the operation of the system. As a result, he can always be led to a safe use of the communication device, which relieves him of a lot of responsibility for incorrect operation of the communication device.
  • Escalation levels can be implemented in the communication device, which range from unrestricted normal operation to warnings and restrictions on functionality to automatic intervention in the functions that can be triggered by the communication device or the system being stopped.
  • the functionality is changed in such a way that an enabling function that can be triggered by the communication device on the system is forcibly deactivated.
  • any consent function given by the user is automatically canceled and cannot be reactivated. This prevents the operator, for example, from carrying out safety-relevant traversing movements in a system, for which he no longer has enough time on the communication device. Safe plant operation is always guaranteed.
  • the functionality is changed such that a stop function that can be triggered by the communication device on the system is forcibly activated. This is e.g. a final security level is given to trigger the safe system shutdown if the user has overlooked the remaining battery life despite all warnings before the battery is completely drained and the inevitably associated demolition of the radio link relinquishes control of the mobile communication device.
